Egypt's military rulers have sped up preparations for a presidential election, after protests calling for a faster transition from military to civilian rule.The election would be Egypt's first presidential vote since last year's popular uprising that ousted longtime leader Hosni Mubarak. Opposition activists who want an end to military rule threw stones at police guarding the Interior Ministry on Monday, as police fired tear gas and set up concrete blocks to keep protesters away from the building.
